What is DaaS (data as a service)?
DaaS, short for data as a service, means a provider keeps data current and customers reach it on demand instead of buying a static file.

Definition
Data as a service (DaaS) is a model in which a provider hosts and maintains data and customers access it on demand, through an API, a feed or a cloud data share, usually on subscription. The buyer gets current data without collecting or storing it.
The idea behind the acronym
The name borrows from cloud computing, where NIST's widely cited definition sets out service models such as software as a service. The common thread is that the customer uses something the provider runs, rather than installing or keeping it. With DaaS, the thing is data: company records, prices, weather, locations, risk scores. The provider collects, cleans and updates it; the customer queries what it needs when it needs it.
Beware a naming clash. In IT, DaaS also stands for desktop as a service, virtual desktops hosted in the cloud. Search results mix the two. This page is only about data.
How it is delivered
- API: the customer's software requests records as needed, often billed by call or by tier.
- Scheduled feed: new or changed records land in the customer's storage on a schedule.
- Cloud data share: the customer queries the provider's live tables inside the same warehouse, as Snowflake's sharing and AWS Data Exchange's Redshift and S3 options allow.
- Web application: a search interface on top of the data, which blurs into software as a service.
Worked example: from archive to service
Suppose an agricultural cooperative runs a network of private weather stations across its members' farms. A crop insurer first asks to buy five years of history. That is a one-off dataset licence. Then the insurer asks for daily updates to price new policies. Now the cooperative is considering DaaS: it needs reliable uptime, an API or a daily file drop, a support contact when a station fails, and a subscription agreement instead of a single payment.
In this illustration, the cooperative may not want to run a service. A broker could help it compare options: sell the history once and stop, partner with a provider that already runs weather feeds, or list the feed on a cloud marketplace that handles delivery. Each route keeps the cooperative as the source while shifting the operational burden differently.
DaaS compared with nearby models
| Model | What the buyer gets | How it is paid for | Seller's ongoing work |
|---|---|---|---|
| Data as a service | Live or refreshed data on demand | Subscription or usage | High: uptime, updates, support |
| One-off dataset licence | A fixed copy under licence terms | Single fee, sometimes staged | Low after delivery |
| Software as a service | An application to use | Subscription per seat or usage | High, but on software rather than data |
| Data marketplace listing | Access via a platform catalogue | Through the platform | Medium: the platform handles delivery and billing |
What to check before buying or building DaaS
- Rights: a subscription is still a licence. Check permitted uses, caching limits and what must be deleted on cancellation.
- Freshness and coverage: how often records change and how gaps are reported.
- Service levels: uptime commitments and what happens when the API fails.
- Lock-in: schemas and identifiers differ between providers, so switching can be costly.
- Personal data: many DaaS products in sales and marketing contain contact details, which bring privacy and registry duties.
Where this site fits
Most people searching for DaaS want a provider to buy from. We don't sell data feeds. This site is for people who broker datasets between companies, including deciding whether a seller's data should become a service, a marketplace listing or a single licence.

Questions people ask
What does DaaS stand for?
In data work it stands for data as a service. In IT infrastructure the same letters often mean desktop as a service, which is unrelated hosted virtual desktops.
What is the difference between DaaS and SaaS?
SaaS gives you software to use. DaaS gives you data to use in your own software. Many products mix both, such as a sales database with a search app on top.
What are examples of DaaS?
Company and contact databases accessed by API, financial market feeds, weather and geospatial feeds, and datasets shared live through cloud warehouse marketplaces.
Is DaaS the same as a data marketplace?
No. DaaS is a delivery model one provider uses. A marketplace is a platform where many providers list offers, some of which are DaaS subscriptions.
How is DaaS priced?
Usually by subscription tier, by number of records or API calls, or by a mix. Terms on caching and reuse often matter as much as the headline price.
